State sync doesn’t work due to Block.Header.AppHash #174

Closed burningxxx closed 2 years ago

As hard we tried we were not able to make state sync work for starnamed, you can reproduce the problem by trying to state sync from our RPC node. Below is the configs.

sudo systemctl stop starnamed && starnamed unsafe-reset-all

SNAP_RPC="http://rpc2.nodejumper.io:34657"

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

peers="3180fdc5e477e675acd22e63477ce3a2db20edf9@rpc2.nodejumper.io:34656"
sed -i -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" ~/.starnamed/config/config.toml

sed -i -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \
s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \
s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" ~/.starnamed/config/config.toml

sudo systemctl restart starnamed && sudo journalctl -u starnamed -f --no-hostname -o cat

Here's the error that we faced:

We were using v0.10.13 which seems to be the latest stable binaries. We also tried to state sync from v0.11.5 without any luck. Let us know if you need any further assistance on fixing this.
